For the most part, the two comedic partners in crime, Gad and Hart, couldn't be more lighthearted when it came to the subject of the big day. We played a wedding word association game with them, and the word "Open bar" triggered Gad to say "Necessary" and Hart quipped "Tragic."

As for the word "Monogamy," Gad said "complicated" and Hart added the punchline "for women." And let's not forget "honeymoon" where Gad was the more the romantic, answering "perfection," and Hart got straight to the point: "sex pad" he replied, and followed up with calling the wedding night a "themed sex pad."

The two funny men let brides in on a little secret, too — your guy will never say he doesn't like something when it comes to big-day planning. "When you're bride-to-be picks out a wedding dress, you would never tell her if you don't like it ... if you don't like it you just got to say you love it," Hart explained.

"I think it goes for everything, I think a groom would never tell you no about any of it because it will be a mess otherwise," Gad added.

Hart hilariously disagreed with his buddy. "I'll say no when it comes to that check!" Hart joked. "Oh you spending too much goddamn money, No! No no no no no — that's it!"

As for Cuoco-Sweeting, who married Ryan Sweeting a little more than a year ago, she explained she's the opposite of her high-maintenance character Gretchen. "I completely put my head in the sand [while planning my own wedding]. I was like, 'I'll show up New Year's Eve, just get it done.' I'm just not that way, I'm like that way with everything," she explained.

And her one bit of advice for engaged ladies? If you turn into a bridezilla, you will freak out your future hubby. "You don't want to turn on the husband-to-be — keep him happy don't turn on him be careful with your friends, they're only trying to help. You got to kind of relax a little bit," Cuoco-Sweeting said.
